AAll great inventions, discoveries and innovations began from a theory, hypothesis or belief.
Thomas Edison invented the incandescent bulb by conducting a detailed analysis of the whole electric lighting system based on Joule's and Ohm's laws.
According to Maxwell (2005) students find the theoretical framework a daunting task and feel intimidated by the notion of theory.
'Theoretical framework' consists of two key words 'theoretical' and 'framework'. In some instances, one theory may be sufficient to explain the phenomenon you are studying while in other instances a combination of theories may be developed as a unique framework of several theories or models.
The theoretical framework is also like the electricity in a house which must flow thorough all rooms in the house.
For example, if you are studying about 'leadership styles and job satisfaction', you will discuss a theory or a combination of theories on leadership styles and job satisfaction which will be aligned to the problem statement, purpose, significance, research questions / hypotheses and methodology.Without doubt, there are hundreds or perhaps thousands of articles, thesis, dissertations, reports and books in the area you are planning to study.Obviously, you are not expected to read all of them.You have to decide which among the abundant works you should include in this section of Chapter 2.Perhaps the following guidelines will help:after having done the above for all the articles, reports, theses, dissertations and papers you have read, GROUP them into the categories - e.g.The pillars, beams and foundation combine to support the house.Similarly, the different theories or models combine to form the underlying foundation of your study, combine to explain the phenomenon being studied, combine to justify why the study should be conducted and what is does not explain.Similarly, your study should be based on a theoretical framework that explains the phenomenon you plan to investigate.in Chapter 2 without knowing how these theories are related to the problem statement, research questions, hypotheses and methodology.At undergraduate level literature reviews can be a separate stand alone assessment.The literature review is generally in the format of a standard essay made up of three components: an introduction, a body and a conclusion.
